Fabric Fit Tip!

Different fabrics can make a difference in how your suit fits. Check out our fabric guide below to learn more.

Swimsuit Fabrics

  • Jolyn swimwear Foreverever fabric icon

    Foreverever

    Consider sizing up

    Our classic Foreverever® fabric is loved by athletes for its durability. By design, it has the least stretch and is the most structured of our fabrics, so if you're in between sizes or prefer a more relaxed fit, we recommend sizing up from your usual size in other brands.

  • Sea-Flex performance swimwear fabric icon

    Recycled Sea-Flex

    True to size

    Made of recycled fishing nets and other discarded nylon, Recycled Sea-Flex is a chlorine resistant performance fabric with the perfect blend of lifestyle comfort and athletic support. It has a soft hand feel and more stretch than Foreverever.

  • Spacer, thick swimwear fabric icon

    Spacer

    True to size

    Our thickest fabric, Spacer feels almost like a lightweight neoprene wetsuit - making it great for compression and durability.

  • Surftec

    SurfTec

    True to size

    Our softest and stretchiest sea fabric to date, with calculated stretch and recovery to make it comfortable but still hold shape. Made out of 100% recycled materials.

Measurement Guide

Torso

The most important for finding your accurate one piece size

Measure from the top of your shoulder over the fullest part of your bust, through your legs and around, up your back to the starting point.

If you are in between torse measurements or know your torso runs long, we recommend sizing up!

Bust

Measure around the fullest part at the bust.

Waist

Measure around the smallest part of the waist.

Hips

Keep measuring tape parallel to the floor and measure around the fullest part of the hip.
